Consistent Control of Damaging Grass Weeds in Barley

Aggressor® AX herbicide offers solutions to the toughest grass weeds in barley. Aggressor® AX herbicide is a Group 1 herbicide that provides consistent control of problem grass weeds like ryegrass, brome grass, barley grass and wild oats. Previously, such levels of control could only be achieved in crops like pulses and canola. Aggressor® AX herbicide has been specifically formulated to provide a high degree of crop safety to CoAXium® barley varieties whilst not compromising on the robust control expected of similar Group 1 herbicides.

Used in conjunction with CoAXium® varieties, Aggressor® AX is a valuable new tool for consistent control of tough winter annual grass weeds including Group 2 resistant biotypes. Aggressor® AX herbicide provides growers with greater crop and chemical flexibility and another rotational option in programs to control problem grass weeds.
